somewhat oblique shape of the outei' segments in certain of his 

 Indian forms indicated that they belouged to a fingered leaf. 

 There is no doubt that the arrangement of these segments is 

 characteristic of the plant, and the fact is well defined by Morris,* 

 who remarks that the four or five pinnules arise in a flabellate 

 form from a common rachis. 



The fructification was unknown to Schenk at the time of his 

 earlier writings, but later f he describes the fruit as spherical or 

 oval, and smootli or hirsute. NathorstJ also discovered what he 

 believed to be the fruit of Sagenopteris undulata, in the Swedish 

 Mesozoic beds, as small spherical bodies plentifully scattered 

 throughout the shale. 



Lindley and Hutton,§ in figuring both the lanceolate and oval 

 leaves of their aS'. Phillipsii, suggested that the longer leaves of 

 their Fig. 2 might be the fruit-bearing, and the oval fronds the 

 barren. 



Touching the relation of Sagenopteris to Glossopteris, Bunbury|| 

 long ago, agreeing with Zigno, doubted the wisdom of their 

 separation. He remarks — " Notwithstanding the difference in 

 the composition of the frond between the typical species of 

 Glossopteris and Sageno2)teris, I yet agree with De Zigno in 

 doubting whether the two genera are sufficiently distinct. In 

 specimens of Sagenopteris Phillipsii from Scarborough, I find the 

 venation so similar to that of the Australian Glossop)teris, that it 

 would be very difficult to found a generic difference upon this 

 character. . . . The fructification of Sagenopteris is still 

 entirely unknown ; and it is possible that, when discovered, it 

 may prove the two genera to be quite distinct." SchenkH retained
